AIn theaccompanying drawings I have used the reference numeral 10 toindicate generally thefioor of a box car which has the outside wall 11,with the ordinary door opening with the upright door frame posts 12 and13.

I have shown also at the top of the car 14 a'diagonal brace 15. Outsidethecar the ordinary `sliding door, nothere shown, and forming nor partof my invention Is used. My improved grain door is made. in threesections superimposed one above the other,

. and I will now describe the lower section.

The lower door section comprises a door member 16 which slides in agroove 17,- indicated by dotted lines in Fig. 1,v in the floorSpecification of Letters Iatent.

10 of the car, from'its position for closing the door opening toposition received in the car on the inside of the outer wall thereof.

The following means are provided for supporting the door section 16 forsliding it: At the upper end of the door section 16 is provided anoutwardly extending stripor member 18 having at its outer end adownwardly extending flange 20. Spaced longitudinally along'the car sidefrom the upright post 13 is a small post 21 shown by dotted lines inFig. 1. The posts 12, 13 and v21 are provided with several series ofhorizontally alined transverse slots or recesses 22.

One series of the recesses 22 is arranged in a horizontal linesubstantially on aline with the upper edge of the lower door section 16.In reach of 'the recesses 22 is mounted av suitable bracket 23 having apair of bearings 24. In each pair of bearings is j mounted a shaft 25.On each shaft 25 near its outer end is a roller 26 and spaced inwardlyfrom the roller 26 is a roller 27 on which travels the Youtwardly member18 of the door section16.

The roller 27 is formed with a reduced portion 28 at its outer end onwhich travels the flange 20, as illustrated in Fig. 2. `It will thusbe'seen that the door section 16 may slide freely on the roller 27 fromits closed position, shown in Fig. 1, to its position on the inside ofthe car. The door section 16 is provided in its lower central p0rtionwith a suitable opening 29, indicated by dotted lines in Fig. 1.

A suitable small sliding unloading vdoor 30 is provided for covering theropening 29.

The door 30 is arranged to slide on the inside 'of the door section 16between suitable upright guides 31, illustrated particularly in Figs. 1,4 and 8.

On the outer surface of the lower part of the door 30,is a slot orrecess 32 for permitting the door 30 to be raised in its 'guides by acrow bar or otherwise. f

Secured to ythe outer surface of the door section 16 is a spring clipdeviceA 33, shown in Figs. 3 and 1, which has on its free end a pin 34.One end of the spring clip device extending is pivotally mounted on thekdoor section 16, so that said clip may swing laterally. l

kThe door section 16 1s provided with an opening-to permit the insertionof the pin 34 through said Vdoor section, so that when the discharge orunloading door 30 isin its lrVhen it is desired to open the door 3()`when the car is loaded, the operator holds the lower end of the springclip 33 outwardly `withdrawing the pin 34 from the opening therefor inthe door section 16, and

preferably swings the clip 33 laterally somewhat, as illustrated bydotted lines in Fig. 1,

so that the pin can then not reenter its opening inthe door section 16.

The door 30 is then raised by means of a crow bar ory the like and theVgrain can flow out below the door 30. Y

Near one upright edge of the door section 16 there is provided asuitable locking device.-

Spaced laterally from the upright mem- Secured to the inner surface ofthe upright member 35 is a strip 36which projects inwardly intothe carat 37, and thence longitudinally along the car as at 38 for forming akeeper for the edge of the door sections.

Secured to the strip 36 is one end of a catch device 39 which extendsthrough the portion 37 of the clip 36 and terminates in a catch 40,which is designed to enter and coact with a suitable recess 41 in theouter surface of the door section 16.

The main portion of the catch device just described is made of resilientmaterial.

' For loperating Vthe catch device for discharging the car, there isprovided a slide rod 42 slidably extended through the side of the car,having at its outer end a ring 43, and having its inner end pivoted to`the catch member 39. .Y In the use of the door section 16, assume thatsaid section is closed and it is desiredv to take the grain out throughthe door opening therein, the operator pulls the lower end of the springdevice 33 outwardly until the pin 34 releases the discharge door30,whereupon that door may be raised. lVhen the door 30 is closed it ma;7be locked in position by means of the pin 34.

If it is desired to openl the. door section 16,'the operator grasps thering 43, pulls the slide rod 42 outwardly for releasing the catch 40from engagement with the notch 41, whereupon the door 16 may beslidalong- V'side Vthe vcar Lon the interior thereof and opened.VV

. Above the door section716 is a door section 44, and above the doorsection 44 is a door section 45 similarly constructed.,l

. f VIt isthought that a description of the door section 4i win beS11-freiem ai 'describe' both sections 44 andr45. 1 l

The door section 44 is arranged so that its lower edge noverlapsthe'door section 16 on outer end, terminates in a downwardly err-Vtending flange 47 Vwhich travels on the rollers 26 on one-horizontalseries of said rollers.

At the upper edge'of said door section 44 is an outwardly.extendingmember 1Sd simi.- lar to the member 18 Vand terminatingin a downwardlyextending flange 20EL similar-to the Vflange 2O which travels on thereduced portion 28y of one horizontal series of the rollers 27. Y

The door sections 44 and 45 are provided withlocking devices similar tothat already .describedfor the door section'16.

`On the outer surface of each door section is a pivoted handle 49.`Onthe inside of the carthereis providedspaced inwardly from the uprightposts, hereinbeforementioned, a grain shieldffwhich terminates above thebottom of the carY so that yif any grain should worl .behind theshield'` it.4 would drop out the bottom of the shield when the load ofgrain is removed fromthe car. Y

` In the practical use of my i provedcgrain door, it will be understoodthat `ordinarily the door section 45 will be leftopen, and

the door sections 44 and 16V closed while the car is being loaded, andwhen the lcar is loaded .the door section 45 will be closed.

When the car is unloadedthe door section 45'may be opened by sliding itV alongside the car to position behind the vshield 50 and a spikeinserted, or if desired, the car may l be unloaded by Vopening the door30.'. -When my improved grain door ;isnot in useV or when the car isusedfor purposes other than hauling grain, the door sections 16, 44 and45 are slid to position'behind the shield 50 and the side of thecarwhere they will not be injured by the contents of the. car.V

It will be notedthat the arrangement of Ythe flange 2O with the largepart of the roller 27 prevents any inner movement ofthe door sections atthe upper portion thereof; and

that the iiange 20 serves to prevent any inner i movement of the lowerdoor section on account of the fact that the flange 20 stands in thepath of the flange 47 kfor preventing any Y such inner movement. Y Somechanges may be made lin the construction andl arrangement-of the partslofl my improved grain door without departing from the essential featuresand purposes A thereof, and it is -my intention to cover by, fmy claimsany modified forms of structurev or use of mechanical equivalentswhichmay Y be. reasonably included within their scope.

I claim as my invention:

1. The combination of a car having a side wall with an opening therein,and having inside said wall upright posts with horizontally alinedinwardly opening recesses therein, a plurality of doorl sectionsarranged in vertical succession having outwardly extending flanges attheir horizontal edges, and downwardly extending flanges at the outeredge of the first described flanges, whereby said flanges may bereceived in said recesses to permit horizontal reciprocation of thesections relative to each other and tothe posts and movement in otherdirections may be limited. Y

2. The combination of a car having a side wall with an opening therein,and having inside said wall upright posts provided with transverserecesses, guide rollers in said recesses, a pair ofrdoor sectionsarranged one above the other and arranged to slide from position forclosing said door opening to osition alongside the interior of the car ajacent to said upright posts, part of said guide rollers having reducedportions, said door sections having inwardly extending members providedwith downwardly extending flanges adapted to rest on said reducedportions and to be held against inner movement inthe wall by the largerportions of the guide rollers which have the reduced portions, said doorsections being arranged one above the other with the lower end of theupper section overlapping the upper end of the lower section, and anoutwardly extending member near the lower edge of the upper sectionresting above the outwardly extending member of the lower door section,and having at its outer end a downwardly extending Harige adapted torest on some of said rollers.
